1929. Serial N0.'359,565 y This .is a division of my' application forpatent, Serial No. 53,182, led August 28,. 1925 on a motor operatedcasting device.

This invention relates to a pump especially for filling stereotypeprintingplate molds, although capable of use for other purposes.

The principal objects of the invention are to provide for the operationot the pump by power-operated means, and the automatic shuttingoilf o1"said means whenk the desired object has been accomplished so as-not torequire' attention by the operator tor the latther objects andadvantages of the in- Reterence is to be had to the vaccompanyingdrawings, in which y A, f l Fig. 1 is a plan of a stereotype platecasting pump constructed in Vaccordance with this invention, shownWith-the mold closed and ready 'for Afilling, and 1 Fig. 2 is a sideview of the .pump mechanism partly in section on the line 2-2 of Fig. 1.Y

Heretofore it hasbeen Vcustomary to op-V molds with metal by a.continuousiy operating `motor from-which the pump is disconnectedV tostop the pump. This invention is designed Jfor usev ona machine of thistype in which the motor itself is stopped whenever the pump is to bestopped.

f The pump P for supplying metal to the mold may be of the usual orany'desired type, except that it has the usual piston 17 and piston rod16 adapted to beoperated vertically to force enough metal upwardlythrough the spout 11 to cast a plate Vat one Y operation of the piston.

I use a motor 12 connected to a worm 13 which operates a segmental wormwheel 14. A Vlever 15 turns with the wheel and thus or lowers them. Itwill be understood that turning the segment 14 in one direction raisesthe piston and turning it back lowers it, and that in the latter'caseenough metal is forced out of the pump chamber 18 into' the mold to casta complete plate as is well 450 understood in this art.

'in rig. 2.

operated byanarm 19`fand by a'link y2()V and handle gripl 21.' Theleverl 15 isv equipped with two pins 9 `and 10 which cause 'the y switchhandle tojturn vwhen thekp'iston has reached its extreme'position atieitherend of the stroke.

- Thefoperation of this part of device is vvery-simple. -Afterthemold'rC B is closed as shown in' Fig.*1 theoperator vpulls the handlegrip 21 forwardf- This -`causes the' switch 8 to close and the motor12to rraise the vpump piston. At theV end of the pump stroke the parts19,20vv and *21j are Vmoved past their originalposition Vby the 'pin 9acting'Y on they switch`fhandlef19." In

thiscase the motor12`in'stead of",` being stopped, is reversed as thepin`9.movesl the handle 19 beyond Vneutral into its extreme position.lThe piston-isreturned'to its original' position, after having 'forced .acharge of lmetal into the-mold. At theh'e'nd oi the reverse stroke," thepin 10 moves'the switch `handle back intol neutrall position and stopsthe motor Vand pump in thev position shown When the plate vhas set, theoperator causes the ycasting boxto opensc that the plate can be. removedand 'the kmatrix changed if desired. No manipulation of the' 'handle 21is necessary. Inthis way the operation required for charging themold ooVis vcontrolled by the handle 21 andthe stopping of the parts isautomatic so that no Aattention is required except `to start them.

`This f Ysimplifies the operation considerably A'and reduces the amountot attention and' supervision required inthe casting of plates insmallplants." 1"
